Poland is moving forward with a major compliance change: mandatory electronic invoicing (e-invoicing) through the National e-Invoicing System (KSeF). This reform will transform how businesses issue and receive invoices.
This reform aligns with broader EU efforts to digitize tax and accounting processes for greater transparency and efficiency.
Poland’s Ministry of Finance has set a phased implementation schedule for mandatory e-invoicing under the revised VAT rules:
KSeF becomes mandatory for large VAT taxpayers with annual turnover exceeding PLN 200 million (2024 sales).
Mandatory for all other VAT-registered businesses (B2B transactions).
Extended mandate to micro-enterprises and smallest economic units.
Important: Receiving e-invoices via KSeF is required for all taxpayers from February 1, 2026 — even before the full invoicing obligation applies to all.
From these dates onward, companies with operations in Poland must:
This shift isn’t just a technical upgrade — it’s a regulatory requirement affecting all stages of invoicing workflows.
Poland’s move toward mandatory e-invoicing aims to:
Improve tax transparency and reduce VAT fraud.
Accelerate and automate invoicing processes across business ecosystems.
Align accounting practices with modern digital standards.
E-invoicing is no longer optional — it’s central to doing business with Polish partners and authorities.

/in eInvoice NewsInvoice transmission: The contracting parties must agree between themselves under civil law which permissible electronic invoice format and which permissible transmission channel is to be used.
Receipt channels: An e-mail inbox is sufficient for the legally compliant receipt of electronic invoices. Alternatively, interfaces or portals are also permitted.
In the long term, the transmission channels will be reviewed as part of the VIDA implementation, with more specific requirements being defined if necessary.
Sanctions: From the start of the obligation (2027 or 2028), ‘other invoices’ (e.g. paper or PDF) will no longer be eligible for input tax deduction. Additional penalties for refusing to accept an e-invoice are currently not envisaged. However, if the recipient refuses to accept the e-invoice even though the sender has demonstrably endeavoured to transmit it correctly, the recipient will be in default.
